Hultsteins present carbon-saving solutions for cool operators at RTX Expo 2023


Hultsteins, the Swedish and UK refrigeration systems manufacturer are showing their Ecogen Cost Saver fitted to a Volvo LNG gas tractor unit at this year’s Road Transport Expo 2023.

*RTX takes place from 28-30 June at NAEC Stoneleigh, Warwickshire and is completely free to attend and to park.    

Ecogen is an electric-hydraulic drive system that transforms diesel fridge units into electric operation when coupled to the tractor. It uses an engine PTO from the tractor engine to generate a constant 400V of electric to run the fridge on its built-in electric motor.

”The Ecogen Costsaver is a sustainable solution that is retrofitable. It allows operators to run their fridge units on electric when coupled to a tractor; it  drives down carbon emissions by around 80%, slashing DPM by 98% and reduces NOx by 400% . It will also reduce R&M on the diesel engine of the fridge and cut fridge running costs” says Graham Usher, Managing Director, UK and Ireland.

”We look forward to welcoming a wide cross section of visitors from the temperature-controlled and retail sectors, who will have the opportunity to see a live demonstration of the Ecogen running on an LNG tractor unit – Cooling on Gas! The tractor will be coupled to a G&A double deck trailer.”
